Query expansion using the UMLS Metathesaurus

A R Aronson et al. Proc AMIA Annu Fall Symp. 1997.

Abstract

Recent work has demonstrated the importance of query expansion for improving retrieval effectiveness when applying statistically-based systems to MEDLINE citations. The research has suggested the use of retrieval feedback for enhancing the original text of users' queries. As an alternative method of query expansion, we propose the use of the MetaMap program for associating UMLS Metathesaurus concepts with the original query. Our experiments show that query expansion based on MetaMap compares favorably with retrieval feedback. We conclude that the optimal strategy would be to combine the two techniques.
